2. MANET/001 Wireless networks: The networks that use wireless transmission for communication links Introduction Wireless Ethernet Satellite Cell phones (= a transceiver + computer + telephone) (= a big repeater in the sky) Two types of wireless networks Wireless networks  Those with fixed infrastructure  Those without fixed infrastructure (Ad Hoc Wireless NW) CS 447 Networks and Data Communication

3. MANET/002 Primary differences from “wired networks”  Each node (especially “terminal node”) can move  Data transmission by broadcast (local broadcast) - Network topology dynamically changes - Network membership dynamically changes Make routing a difficult job Transmitting node Destination node Local Broadcast A wireless network CS 447 Networks and Data Communication

4. MANET/003 Primary differences from “wired networks”  Each node (especially “terminal node”) can move  Data transmission by broadcast - Network topology dynamically changes - Network membership dynamically changes Make routing a difficult job Transmitting node Destination node Local Broadcast Is this local broadcast? Is this global broadcast? (YES) (NO) CS 447 Networks and Data Communication
